Install the intake manifold assembly (2).
Notice: Refer to Fastener Notice (See: Service Precautions\Vehicle Damage Warnings\Fastener Notice) .

Important: Tighten the intake manifold to cylinder head retaining bolts (1) in a circular pattern starting at the center (long bolts) and moving outward.

Install the intake manifold to cylinder head retaining bolts (1).
Tighten the bolts to 23 N.m (17 lb ft).
